The speakers in the banquet hall use devices with a large range to listen to a piece of music. The best song has a large sound layer beat, the best song presents chords, and the sound quality that can be heard by the big chords. If a speaker can perfectly show the difference and realism between low and high tones, then it is clear that this speaker can still pass the test.
Try to listen to the music you know. The music you know will leave a more in-depth image in your mind, so you can hear the sound box in a moment. If you audition with your own CD business, you have the right to refuse. Because he may cover up the shortcomings of the speaker with the shortcomings of the CD itself.
When customers pick up the idea of low noise, they must bring the CDs they often listen to, such as the music they know, so as to distinguish the good from the bad with an objective sound.
